TGW Threaded Hydraulic Quick Couplings
Application
It is designed for heavy duty applications involving very high pressures and severe pressure pulse conditions, Such as Hydraulic jacks, Hydraulic hammers, Construction plant, mobile equipment, demolition and agricultural industries .
Characteristics
Ball bearing offers access to connect with KSNV series male half .
Thread -to -connect with double shut -off valving .
Self locking connection mechanism prevents accidental disconnection caused by vibration .
New valve design , it cans resistance damage from high flow and the pressure that providing advanced performance.
Machined from solid steel barstock for durability .
The TWG Series employs a threaded sleeve locking mechanism , mates with matching male threads on the nipple . The two halves must be manually threaded together for connection .
New chrome plating treatment provides advanced anti-rust performance .
Hard ,chrome alloy balls are used for valving . They Are spring loaded for positive seating of the valve .
This Anti-Blowout bonded seal is designed to prevent blow -out or damage during severe service conditions .
Compatible with GROMELLE 6000 Series and HOLMBURY TGW Series

Selection Steps
Hydraulic quick coupling selection steps: Determine system pressure, flow rate, oil type, and environmental parameters; select push-pull or twist-lock type based on operating conditions; verify interface specifications (e.g., SAE J518) to ensure complete compatibility; choose carbon steel for normal environments and stainless steel for corrosive environments. During installation, clean the flange, align, and tighten bolts evenly. Low-pressure venting is required for the initial connection. Regularly inspect the appearance; cover with a dust cover when disconnecting; and replace seals annually to effectively prevent leaks. Accurate selection and standardized maintenance ensure long-term reliable system operation.
